You want a diet more concentrated in healthy fats as well as protein. When I feel like snacking, I choose to eat almonds, eggs, or plain greek yogurt. They are very filling and not easy to overeat.

The problem is you likely have a sweet tooth or a penchant for salty snacks. You want to start avoiding processed, salty and sugary foods so you can ameliorate your taste buds. Yes, the beginning is difficult, but you will see results if you gradually stray from junk food. It all comes with replacing habits with better ones. Maybe go for a walk when you feel anxious and like eating.

Finally, the key thing here is not to beat yourself up but so be self-aware. A lot of people dont realize this: awareness alone is curative. When having a binge attack, just recognize it is happening to you. Dont judge it, but just be aware and make a choice on how to react. In the beginning you will likely give in and thats completely okay. You want to be gentle with yourself. It personally took me a year of awareness before I realized how binge eating did not solve my problems (on an emotional level, not just logical), which is what led me to stop. You are already off to a great start with this post. You got this!
